Use PFunctor.mk directly for OracleSpec

[quangvdao]

Summary

• define OracleSpec.toPFunctor directly with PFunctor.mk
• remove the obsolete PFunctor.ofFamily case from the structural registry-key normalizer
• pin PolyFun to merged cleanup PR PolyFun #73, commit 1f7f477c9701f7606841bb1638dcffb9b2359d62

Rationale

PFunctor.ofFamily was only a reducible wrapper around the structure constructor and has now been removed upstream. Using PFunctor.mk preserves the existing definitional round trips while removing one reducible declaration from the normalization path.

Stack and conflict audit

This PR targets the current head of #490 (dtumad/reducible-oraclecomp). The newer draft #492 is also stacked on #490, but touches none of this PR's four files, so the branches can proceed independently.

🤖 PR Summary

⚠️ PR title does not follow conventional commit format type[(scope)]: subject. Got: Use PFunctor.mk directly for OracleSpec

The PR updates OracleSpec.toPFunctor to use PFunctor.mk directly, removing dependency on the now-removed upstream PFunctor.ofFamily. Correspondingly, the symMatchKey tactic is adjusted to not unfold ofFamily. PolyFun dependency is pinned to a compatible commit. No new sorry/admit are introduced.

📋 **Additional Analysis**

The diff updates the PolyFun dependency, adjusts OracleSpec.toPFunctor and symMatchKey to follow upstream API changes, and removes a stale reference to PFunctor.ofFamily. No style, documentation, or process violations were found.

📄 **Per-File Summaries**

• VCVio/OracleComp/OracleSpec.lean: In OracleSpec.lean, the definition of toPFunctor was refactored: instead of calling PFunctor.ofFamily spec, it now directly constructs a PFunctor via PFunctor.mk ι spec. This changes the internal representation but preserves the semantics; no other definitions, theorems, or sorry/admit are affected.
• VCVio/ProgramLogic/Tactics/Common/Core.lean: The symMatchKey tactic helper in Core.lean was modified to no longer unfold PFunctor.ofFamily when computing the key for Sym's discrimination-tree matching. The docstring comment above the function was updated accordingly, removing the mention of PFunctor.ofFamily both from the list of unfolded wrappers and from the note about not using Sym.preprocessType. This change ensures that the key computation matches only the structural patterns produced by Sym.mkPatternFromDeclWithKey for OracleComp, OracleQuery, and OracleSpec.toPFunctor, aligning the implementation with the original intent described in the docstring.
• lakefile.lean: The only change is that the pinned commit hash for the PolyFun dependency was updated from a65a9ab83ad42034229d379940bbeed2f44831df to 1f7f477c9701f7606841bb1638dcffb9b2359d62. This matters because it changes the precise version of that external library used by the project.

Incremental Rebuild Signal

• Warm rebuild saved 707.97s vs clean (161.90x faster).

This compares a clean project build against an incremental rebuild in the same CI job; it is a lightweight variability signal, not a full cross-run benchmark.
